Description
Technical Field
[0001] This utility model relates to a pressing device, and more particularly to a terminal pressing device, belonging to the field of electrical connection element processing equipment. Background Technology
[0002] In the field of electrical connections, terminals, as core connecting elements, have a direct and critical impact on the stability and safety of subsequent connections due to the quality of their crimping. Currently available terminal crimping devices still have room for improvement in terms of structural flexibility and practical adaptability: On the one hand, some devices use an integrated design for the terminal crimping platform and base. When different terminal specifications need to be adapted, or when the platform wears out and requires maintenance, the entire device often needs to be replaced. This not only increases maintenance costs but also reduces equipment efficiency. On the other hand, most devices lack a reliable reset structure. After the crimping operation is completed, the guide rod needs to be manually reset, which not only makes the operation process relatively cumbersome but also affects overall processing efficiency to some extent.
[0003] Therefore, there is a real demand in the industry for terminal pressing devices with detachable structures, stable guidance, and convenient operation, in order to better make up for the shortcomings of existing technologies and further improve the efficiency and quality of terminal pressing. Utility Model Content
[0004] The purpose of this invention is to provide a terminal pressing device. This invention can adapt to terminals of different specifications, enabling convenient replacement and maintenance while improving processing efficiency.
[0005] The technical solution of this utility model is as follows: A terminal pressing device includes a base, a terminal pressing platform detachably fitted to the base, a support rod at the rear end of the base, a housing on the support rod, a guide rod passing through the front end of the housing in a vertical direction, a driving mechanism on the side of the housing, the driving mechanism driving the guide rod to slide in cooperation with the housing; a sliding rod at the upper end of the housing, a sliding guide block at the upper end of the guide rod with one end slidably mounted on the sliding rod, a spring connecting part on the upper surface of the other end of the sliding guide block, a spring connecting block at the top of the sliding rod, and a return spring between the end of the spring connecting block and the spring connecting part; a pressing block at the lower end of the guide rod, which cooperates with the terminal pressing platform, and the pressing block is detachably fitted to the guide rod.
[0006] In the aforementioned terminal pressing device, the base includes a first annular clamp, and the first annular clamp has first mounting holes on both sides. The bottom end of the frame rod passes through the first annular clamp and is fixedly connected by bolts passing through the first mounting holes on both sides of the first annular clamp.
[0007] In the aforementioned terminal pressing device, the housing includes a second annular clamp, and the second annular clamp has second mounting holes on both sides. The upper end of the support rod passes through the second annular clamp and is fixedly connected by bolts passing through the second mounting holes on both sides of the second annular clamp.
[0008] In the aforementioned terminal pressing device, the base is provided with a third mounting hole, and the terminal pressing platform is rigidly connected to the base in a detachable manner by bolts and the third mounting hole.
[0009] In the aforementioned terminal pressing device, the bottom of the guide rod is provided with a slot, and the upper end of the lower pressing block is provided with a locking block that cooperates with the slot. The slot and the locking block are engaged to form a fourth mounting hole. The guide rod and the lower pressing block are detachably connected to each other through the fourth mounting hole and screws.
[0010] In the aforementioned terminal pressing device, the driving mechanism includes a gear shaft passing through the housing, and the side of the guide rod is provided with a rack that meshes with the gear shaft; both ends of the gear shaft pass through the housing in the horizontal direction and rotate in cooperation with the housing, and one end of the gear shaft is fixedly connected to a handle.
[0011] In the aforementioned terminal pressing device, guide grooves are provided on both sides of the guide rod, and guide sliders that cooperate with the guide grooves are provided inside the housing.
[0012] In the aforementioned terminal pressing device, the terminal pressing platform is stepped.
[0013] In the aforementioned terminal pressing device, the lower pressing block is T-shaped, and the lower end of the lower pressing block engages with the first step of the terminal pressing platform.
[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a terminal pressing platform detachably coupled to a base and a pressing block detachably coupled to a guide rod. When different specifications of terminals (such as electrical connection terminals of different sizes and models) need to be accommodated, or when the pressing platform and pressing block require maintenance due to wear and deformation from long-term pressing, there is no need to replace the entire equipment; only the bolts need to be removed for replacement. This significantly reduces maintenance costs, shortens equipment adjustment time, improves adaptation efficiency, and further enhances the device's adaptability to different terminal processing requirements. This invention uses a return spring to automatically pull the sliding guide block back to its initial position, thereby eliminating the need for manual reset, simplifying the operation process, and reducing the time consumed in a single pressing operation. Especially in batch terminal processing scenarios, this significantly improves overall processing efficiency. Furthermore, the cooperation between the guide groove and the guide slider ensures that the pressing block is always precisely aligned with the terminal pressing platform, effectively avoiding problems such as terminal pressing deformation and poor connection stability caused by guide misalignment, thus guaranteeing the quality of terminal pressing.

Detailed Implementation
[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0018] Example: A terminal pressing device, configured as follows Figure 1As shown, the system includes a base 1, on which a terminal pressing platform 2 is detachably fitted. A support rod 3 is located at the rear end of the base 1. The base 1 includes a first annular clamp 101, with first mounting holes 13 on both sides. The bottom end of the support rod 3 passes through the first annular clamp 101 and is fixedly connected by bolts passing through the first mounting holes 13 on both sides of the first annular clamp 101. The base 1 is integrally formed from Q235 steel, with a main body of a rectangular plate (300mm long × 200mm wide × 15mm thick). The rear end is welded with the first annular clamp 101 (50mm inner diameter, 5mm thickness). Two M8-sized first mounting holes 13 are symmetrically opened on both sides of the first annular clamp 101. The support rod 3 is a 50mm diameter 45# steel round rod (600mm long). During assembly, its bottom end is inserted into the first annular clamp 101, and the M8 bolts on both sides of the clamp are tightened with an Allen wrench to keep the support rod 3 vertically fixed to the base 1. The support pole 3 is equipped with a housing 4, which includes a second annular clamp 401. The second annular clamp 401 has second mounting holes 14 on both sides. The upper end of the support pole 3 passes through the second annular clamp 401 and is fixedly connected by bolts passing through the second mounting holes 14 on both sides of the second annular clamp 401. The main body of the housing 4 is a rectangular steel shell (100mm long × 50mm wide × 120mm high). The second annular clamp 401 (50mm inner diameter, 5mm thickness) is welded to the back. Two M6-sized second mounting holes 14 are opened on both sides of the second annular clamp 401. The housing 4 is fitted onto the upper end of the support pole 3 (at a height of 500mm from the base). After adjusting the front end of the housing 4 to face the terminal pressing direction, the M6 bolts are tightened to fix the housing 4. A guide rod 5 passes vertically through the front end of the housing 4. Guide grooves 502 are provided on both sides of the guide rod 5. A guide slider 402 that mates with the guide grooves 502 is provided inside the housing 4. The guide rod 5 measures 40mm in length, 40mm in width, and 400mm in height, and is made of 40Cr steel. Symmetrical guide grooves 502, 8mm wide and 3mm deep, are machined on both sides of the guide rod 5. Two corresponding guide sliders 402 (made of wear-resistant cast iron, 8mm × 8mm × 15mm) are welded to the inner wall of the housing 4 to match the guide grooves 502, ensuring that the guide rod 5 slides only vertically without radial offset. A drive mechanism 6 is provided on the side of the housing 4, which drives the guide rod 5 to slide smoothly against the housing 4. Figure 2As shown, the drive mechanism 6 includes a gear shaft 601 (module 2, number of teeth 20, material 20CrMnTi) passing through the housing 4. A rack 503, meshing with the gear shaft 601, is provided on the side of the guide rod 5. The gear section of the gear shaft 601 meshes with the rack 503 (module 2, number of teeth 20, tooth width 15mm) machined on the side of the guide rod 5. Both ends of the gear shaft 601 extend horizontally out of the housing 4 and are rotatably engaged with the housing 4 via deep groove ball bearings (model 6204). A handle 602 is fixedly connected to one end of the gear shaft 601. A slide rod 7 is provided at the upper end of the housing 4. The slide rod 7 is a stainless steel rod with a diameter of 12mm and a length of 400mm. A sliding guide block 8, with one end slidably mounted on the slide rod 7, is provided at the upper end of the guide rod 5. One end of the sliding guide block 8 has a sliding hole with a diameter of 12.5mm, and it is fitted onto the slide rod 7 and can slide along the rod. The other end of the sliding guide block 8 has a spring connecting part 9 on its upper surface. The spring connecting part 9 is a boss with an M5 threaded hole. The top of the slide rod 7 has a spring connecting block 10, which is an L-shaped steel plate with an M5 threaded hole at its end. A return spring 11 (material 65Mn, diameter 6mm, free length 200mm, elastic coefficient 5N / mm) is provided between the end of the spring connecting block 10 and the spring connecting part 9. The two ends of the return spring 11 are fixed by M5 bolts, which keep the guide rod 5 in the upper position in its natural state. The lower end of the guide rod 5 has a lower pressing block 12 that cooperates with the terminal pressing platform 2. The lower pressing block 12 and the guide rod 5 are detachably connected. The base 1 has a third mounting hole 15. The terminal pressing platform 2 is detachably rigidly connected to the base 1 by bolts through the third mounting hole 15. The base 1 has a third mounting hole 15 (two M10 threaded holes per group, with a hole spacing of 50mm). The terminal pressing platform 2 (made of hard alloy, 120mm long × 80mm wide × 20mm high, with terminal positioning grooves machined on the surface) is connected to the base 1 by M10 bolts (25mm long). Different hole positions can be selected for installation according to the terminal specifications, and the platform position can be adjusted. The lower end of the guide rod 5 is machined with a rectangular slot 501 (40mm long × 20mm wide × 10mm deep). The upper end of the lower pressing block 12 (made of Cr12MoV, 50mm long × 30mm wide × 20mm high) is integrally formed with a locking block 1201 that fits the slot 501. After the slot 501 and the locking block 1201 are engaged, an M6 fourth mounting hole 16 is formed. An internal hex screw (15mm long) is passed through the fourth mounting hole 16 to achieve detachable fixing of the lower pressing block 12 and the guide rod 5. The terminal pressing platform 2 is stepped, and the lower pressing block 12 is T-shaped. The lower end of the lower pressing block 12 engages with the first step of the terminal pressing platform 2. The lower pressing block 12 includes a first step and a second step from bottom to top. The base of the terminal is placed on the first step, and the terminal to be pressed is placed on the upper end of the terminal base and in contact with the second step. At this time, the T-shaped bottom end of the lower pressing block 12 is pressed down by rotating the handle 6. Figure 3 As shown.
[0019] This invention utilizes a terminal pressing platform 2 detachably coupled to the base 1 and a lower pressing block 12 detachably coupled to the guide rod 5. When different specifications of terminals (such as electrical connection terminals of different sizes and models) need to be adapted, or when the pressing platform and lower pressing block 12 require maintenance due to wear and deformation from long-term pressing, there is no need to replace the entire equipment components; only the bolts need to be removed for replacement. This significantly reduces maintenance costs, shortens equipment adjustment time, improves adaptation efficiency, and further enhances the device's adaptability to different terminal processing requirements. The invention also features a return spring 11 that allows the sliding guide block 8 to be reset by its own elastic force, thereby automatically raising the guide rod 5 and lower pressing block 12 to their initial positions. This eliminates the need for manual reset, simplifies the operation process, and reduces the time consumed in a single pressing operation. Especially in batch terminal processing scenarios, this significantly improves overall processing efficiency. Furthermore, the cooperation between the guide groove 502 and the guide slider 402 ensures that the lower pressing block 12 is always precisely aligned with the terminal pressing platform 2, effectively avoiding problems such as terminal pressing deformation and poor connection stability caused by guide misalignment, thus guaranteeing the quality of terminal pressing.
[0020] Work process The operator holds the handle 602 and rotates it clockwise. The gear shaft 601 drives the rack 503 to move downward, and the guide rod 5 descends vertically along the guide groove 502. The lower pressure block 12 presses down on the terminal simultaneously. Once the terminal is pressed into place, the operator stops rotating the handle 602, at which point the return spring 11 is stretched. Releasing the handle 602 releases the elastic potential energy of the return spring 11, pulling the sliding guide block 8 to slide upward along the slide rod 7, causing the guide rod 5 and the lower pressure block 12 to rise synchronously back to their initial upper position. The pressed terminal is then removed, and the next pressing operation can begin.
[0021] In summary, this utility model can adapt to terminals of different specifications, enabling convenient replacement and maintenance while improving processing efficiency.
